CHARLES P. ANDERSON, OF BROWN VALLEY, MINNESOTA.

WEBB-DESTROYER.

p Specification of Letters Patent. Application filed November 1. 1967.Serial No400,193.

Patented April 28, 1808.

To all whom it may concern.'

Be it knownthat I, CHARLES P. ANDER- soN, citizen of the United States,residing at Brown Valley, in the county of Traverse and State ofMinnesota, have invented certain new and useful Improvements in VVeedDestroyers, of which the following is a specification.

. This invention is a mach-ine for destroying weeds and grasses in afield, and has for its object to provide a machine of .this kind whichis simple in construction', and reliable and efficient in operation.

The `invention comprises a wheel-driven cylinder armed with spikeswhich` enter the ground and pull up the weeds and Grasses by theirroots. Means are also provided for removing the weeds and grasses fromthe cylinder and delivering the same to a receptacle carried by themachine, which receptacle may be dumped at will bythe operator.

vIn the accompanying drawings, Figure 1 is an elevation o the invention.longitudinal section on the line2-2 ofv Fig. 3. Fig. 3 is a plan view.Figs. 4 and 5 are detas showing the construction of the conveyer andclearer-belts hereinafter referred to.

Referring specifically to the drawings, the supporting-frame of themachine is a-boX- like structure mounted on wheels, and having at itsfront end a seat 10 for the operator or driver. The rear wheels 11 arethedrivewheels, and the front Wheels 12 are for guid ing the machine.Suitable means for attachment of the draft-animals are provided.

Extending between the side-walls 13 of the supporting-frame, and mountedtherein in any suitable manner, is a transverse shaft 14 on which ismounted to rock thereon, a frame which carries the working parts to beherein` after described. This frame comprises angularly disposed beams15 and 16 respectively, the `former of which is pivotally mounted on theshaft 14. At the junction of the beams is a bearing in which is revolubly mounted a cylinder 17 armed withs ikes 18. The beam 15 has bearingsfor the s afts 19 and 20 of sprocket-wheels 22 and 23 respectively, andon said beam is also mounted a supporting-bracket 24 for the bearing ofthe shaft 25 of a s rocket-wheel 26. The beam 16 is provide with abearing for the shaft 27 of a sprocket-wheel 28.- The supporting-frameand associated parts herein described are duplicated on the op ositeside of the machine. Over the sproc ret-wheels Fig. 2 is a' done 22 and23 travels a belt 29 armed with spikes 30. 'Said belt comprises chains31 passing over the sprocket-wheels on each side of the machine, andconnected by cross-slats 32 to which the .spikes 30 are fastened. Theslats lie close together so that the weeds, grasses and dirt 'cannotdrop therethrough. This construction is clearlyillustrated in Fig. 5 inwhich an end and plan view of a portion of the .belt is shown. Aspiked-belt 33 travels over the sprocket-wheels 26 and 28, and said beltis engaged by an idler 34 carried by a bracket 35 mounted yon the beam15. The object of the idler is to guide the belt 33 so that itv willtravel in close proximity to the belt 30 for a purpose to be hereinafterdescribed.

The sup orting-frame of the spiked cylin-l der and be ts is connected bya suitable system of links 36 with a hand-lever 37 in order that thesame may be raised or lowered. The hand-lever is pivoted at 38 to thesidewall 13 of the machine-frame near the seat 104 so as to be in easyreach of the driver, and said lever is provided with the usual latch 39for locking it. The spiked cylinder is thrown into and out of operationby rocking its su porting-frame on the shaft 14 which is by thehand-lever herein described.

-The spiked cylinder 17 is driven by a chain 40.from the rear ordrive-axle 42. The belts 29 and 33 are driven by a chain 40a whichpasses over a sprocket-wheel 41 on the rearaXle and over asprocket-wheel 43 on the shaft 27, and a sprocket-wheel 44 on the shaft20. This chain is provided with a tightener ulley 45 carried by andoperated by a hand-liever 46 pivoted to the side-wall 13 of themachine-frame. In front of the spiked cylinder 17 at each end thereoftravel rolling colters 47 which are carried by the beam 15.

At the rear end of the-machine, at each side thereof, are mountedbrackets 48 provided with bearings for the shaft 49 of sprocketwheels50. On the -rear-'axle 42, at each side of the machine, are looselymounted sprocket-wheels 51. The sprocket-wheels are connected by aconveyer-belt 52 comprising chains 53 which are connectedby crossslats54 spaced apart sufficiently to permit the dirt to drop back on thefield. The details of construction of this belt are shown in Fig. 4which is an end and a lan view of a portion of the belt. On the )racket48 are also mounted the shafts 55 and 56 res ectively, ofsprocket-wheels 57 and 58. On t e rear-axle 42 is made fast asprocket-wheel 59. On the shafts 49 and 55 are sprocket-wheels which areconnected by a chain 60. The conveyerbelt 52 is driven from therear-axle by means of a chain 61. which passes over thesprocketwheels159andl 58, and under the sprocketwheel 57. The motionthus imparted to the shaft 55 is transmitted to the shaft 49 by thesprocket-wheels thereon which are connected byithechainA 60.i Theobject. of this gearing is :to obtainl `the travel. of the i conveyer-belt ini vthe i. required direction. Awhich is opposite towthatfof.,thel travel of the-drive-axle or towardnthe rear end of. the machine.

Atthe rearsendof the machine is pivotally. mounted von. asuital'ilediracket 62 a receptacle 63 .into which the iconveyer-belt 52discharges. To thisireceptacleis;connected a rope .64 which leads to; atrip-lever 65 vpivoted nearithe seat, 10 so as to be in; easy. reach ofthe driver, --whereby the receptacle may be tilted to dump :theload Whenithe spikedv cylinder 17 is=lowered into. operatingposition,;y and `themachine is driveiiyaerosstlreheld, the spikes i8 enterthe ground andpull up the grass and weeds byitheir roots.; Thespikes arefcleared ofthetrashA 'th-us ,pulledup; Aby' the spiked .belt 29 the .sprocket-wheel ibeing so located with res, eet. to the spiked `cylinder that the belt.will) itravelsufliciently. close thereto-for this purpose.Tlie.,belt,and ycylinder travel in-I the same. direction.
